Non-uniform layers are a common and unavoidable phenomenon in the fabrication of pixel organic light-emitting diodes(OLEDs),particularly in inkjet printing(IJP),which often exhibits pronounced coffee-ring effects.However,accurately simulating these non-uniform features in pixel OLEDs remains a significant challenge for existing methods.In this work,a two-step domain decomposition method was proposed to accurately and efficiently analyze pixel OLEDs with non-uniform layers.In the first step,the whole pixel was divided into several non-overlapping regions according to the dipole radiation range,and the classical dipole radiation model combined with the scattering-matrix method was applied.In the second step,each radiation region was subdivided into uniform and nonuniform parts(quasi-uniform parts),and a modified physical model was introduced to correct the reflection coefficient,transmission coefficient,and phase difference caused by non-uniform layers.The proposed method was verified through both numerical simulations and experiments on a typical IJP OLED.The results showed excellent agreement between the simulated and experimental data,with computational efficiency improved by a factor of 182 compared with COMSOL Multiphysics®.In addition,the analysis of the Purcell effect of a single dipole in a truncated Gaussian microcavity revealed the influence of non-uniformity on the microcavity effect.It explains the physical mechanism of the optical effect caused by non-uniformity,providing a theoretical fundament for non-uniform OLED optimization and manufacturing.This method breaks through the limitations of the traditional uniform model and facilitates the optical simulation and analysis of large-area pixel OLEDs with non-uniform layers. 展开更多

Solar power towers(SPTs)are a leading concentrated solar power(CSP)technology,utilizing heliostat fields to direct solar radiation onto a central receiver.Accurate simulation tools are vital for optimizing these systems.This review offers a structured and comparative analysis of simulation platforms used in optical,thermal,and system-level modeling.Tools such as SolTrace,Tonatiuh,and DELSOL are reviewed for their ray-tracing accuracy and computational trade-offs.Thermal and CFD tools,including OpenFOAM,ANSYS Fluent,and COMSOL,are evaluated for heat transfer modeling.System-level tools,such as SAM,TRNSYS,and Dymola,are assessed for techno-economic analysis and control strategy development.Rather than relying on standardized test cases,the comparison adopts consistent evaluation metrics such as modeling scope,integration ability,computational efficiency,and validation status,derived from field-tested case studies and empirical benchmarks.The review highlights that while several tools demonstrate high accuracy and real-world validation,persistent gaps remain in multi-domain interoperability and real-time modeling.Key contributions include a hybrid simulation framework integrating ray tracing and CFD for receiver modeling,a performance-based classification of tools grounded in validated case studies,and a decision-making roadmap for tool selection based on design context.Future directions include AI-based heliostat aiming using IUPSO,surrogate models for heat transfer prediction,and objectoriented digital twin architectures built on SolarTherm with real-time sensor integration to improve predictive accuracy,scalability,and deployment readiness. 展开更多

The capacitively coupled radio frequency（CCRF）plasma has been widely used in various fields.In some cases,it requires us to estimate the range of key plasma parameters simpler and quicker in order to understand the behavior in plasma.In this paper,a glass vacuum chamber and a pair of plate electrodes were designed and fabricated,using 13.56 MHz radio frequency（RF）discharge technology to ionize the working gas of Ar.This discharge was mathematically described with equivalent circuit model.The discharge voltage and current of the plasma were measured atdifferent pressures and different powers.Based on the capacitively coupled homogeneous discharge model,the equivalent circuit and the analytical formula were established.The plasma density and temperature were calculated by using the equivalent impedance principle and energy balance equation.The experimental results show that when RF discharge power is 50–300 W and pressure is 25–250 Pa,the average electron temperature is about 1.7–2.1 e V and the average electron density is about 0.5？×10^17–3.6？×10^17m^-3.Agreement was found when the results were compared to those given by optical emission spectroscopy and COMSOL simulation. 展开更多

We developed a single-particle optical particle counter with polarization detection(SOPC)for the real-time measurement of the optical size and depolarization ratio(defined as the ratio of the vertical component to the parallel component of backward scattering)of atmospheric particles,the polarization ratio(DR)value can reflect the irregularity of the particles.The SOPC can detect aerosol particles with size larger than 500 nm and the maximum particle count rate reaches~1.8×105particles per liter.The SOPC uses a modulated polarization laser to measure the optical size of particles according to forward scattering signal and the DR value of the particles by backward S and P signal components.The sampling rate of the SOPC was 106#/(sec·channel),and all the raw data were processed online.The calibration curve was obtained by polystyrene latex spheres with sizes of 0.5-10μm,and the average relative deviation of measurement was 3.96% for sub 3μm particles.T-matrix method calculations showed that the DR value of backscatter light at 120°could describe the variations in the aspect ratio of particles in the above size range.We performed insitu observations for the evaluation of the SOPC,the mass concentration constructed by the SOPC showed good agreement with the PM2.5measurements in a nearby state-controlled monitoring site.This instrument could provide useful data for source appointment and regulations against air pollution. 展开更多

Light extraction efficiency of organic light-emitting devices has improved by using a nano-sized multi-cathode structure consisting of semi-transparent metal and an optical compensation layer. From the detail optical calculation based on the multi-scale analysis including near-field optics, it was found that surface plasmon loss in the metal cathode is suppressed to less than 10% due to long range and short range surface plasmon coupling between both sides of metal cathode. Not less than 90% of optical power in the dipole emission can be successfully utilized as propagation light. Light extraction efficiency in a phosphorescent device has improved about twice by using the multi-cathode structure. 展开更多

We present the specific ab-initio calculations that detail the variations of perovskite BaZrO3 caused by in-plane strain. Specifically, the internal relaxation, which was not captured in the widely used biaxial strain model, was included in a complementary manner to lattice relaxation. Density functional theory as well as a hybrid functional method based on a plane wave basis set was employed to calculate the lattice structure, elastic constants, electronic properties and optical properties of perovskite BaZrO3. The lattice parameter c exhibited a clear linear dependence on the imposed in-plane strain, but the Poisson＇s ratio caused by internal relaxation was smaller than the elastic deformation, indicating an ＂inelastic＂ or ＂plastic＂ relaxation manner caused by the introduction of internal relaxation. As a result, the related electronic and optical properties of perovskite BaZrO3 were also strongly affected by the in-plane strain, which revealed an effective way to adjust the properties of perovskite BaZrO3 via internal relaxation. 展开更多

For space-borne gravitational wave detection missions based on the heterodyne interferometry principle,tilt-to-length(TTL)coupling noise is an important optical noise source,significantly influencing the accuracy of the measurement system.We present a method for analyzing TTL coupling noise under the joint influence of multiple factors.An equivalent simulated optical bench for the test mass interferometer was designed,and Gaussian beam tracing was adopted to simulate beam propagation.By simulating the interference signal,it can analyze the impact of various factors on the TTL coupling noise,including positional,beam parameters,detector parameters,and signal definition factors.On this basis,a random parameter space composed of multiple influential factors was constructed within a range satisfying the analysis requirement,and the corresponding simulation results from random sampling were evaluated via variance-based global sensitivity analysis.The calculated results of the main and total effect indexes show that the test mass rotation angle and the piston effect(lateral)significantly influence the TTL coupling noise in the test mass interferometer.The analysis provides a qualitative reference for designing and optimizing space-borne laser interferometry systems. 展开更多

This paper presents the design and ground verification for vision-based relative navigation systems of microsatellites,which offers a comprehensive hardware design solution and a robust experimental verification methodology for practical implementation of vision-based navigation technology on the microsatellite platform.Firstly,a low power consumption,light weight,and high performance vision-based relative navigation optical sensor is designed.Subsequently,a set of ground verification system is designed for the hardware-in-the-loop testing of the vision-based relative navigation systems.Finally,the designed vision-based relative navigation optical sensor and the proposed angles-only navigation algorithms are tested on the ground verification system.The results verify that the optical simulator after geometrical calibration can meet the requirements of the hardware-in-the-loop testing of vision-based relative navigation systems.Based on experimental results,the relative position accuracy of the angles-only navigation filter at terminal time is increased by 25.5%,and the relative speed accuracy is increased by 31.3% compared with those of optical simulator before geometrical calibration. 展开更多

Two-photon fluorescence microscopy,based on the principles of two-photon excited fluorescence and second harmonic generation,enables real-time non-invasive in vivo imaging of skin and cells,providing a means to assess human health status.In this paper,a miniaturized two-photon imaging system is designed and fabricated to withstand extreme vibration and shock environments.The mechanical stability of the optical and structural components of the miniaturized probe is evaluated under random vibration and shock vibration tests using finite element simulation methods and ray tracing techniques.During the environmental testing,the maximum stress on the probe is 11.5 MPa,which is well below the threshold for structural failure.The largest structural displacement occurs at the collimator,where random vibrations produce an offset of 10.9μm.This offset is analyzed by using geometric optics and point spread functions.Under the maximum collimator offset,the theoretical resolution,as calculated by the point spread function,shifted from 463.28 nm to 463.48 nm.Additionally,a lateral offset of 127 nm is observed at the center position,which does not significantly impact the imaging performance.Finally,environmental and imaging performance tests are conducted.The system’s measured resolution after the environmental tests is 530 nm,consistent with its resolution prior to testing.Imaging tests are also performed on the skin’s stratum corneum,granular layer,spinous layer,and basal cell layer,revealing clear cellular structural information.These results confirm the device’s potential for applications in extreme shock and vibration environments. 展开更多

METHODS：Fifteen subjects were recruited. The corneal images from optical coherence tomography（OCT）were imported into Matlab software. Five edge detection methods（Canny,Log,Prewitt,Roberts,Sobel）were used to identify the corneal surface. Then two manual identifying methods（ginput and getpts）were applied to identify the edge coordinates respectively. The differences among these methods were compared. Binomial curve（y=Ax2＋Bx＋C）,Polynomial curve [p（x）=p1xn＋p2x（n-1）＋....＋pnx＋pn＋1] and Conic section（Ax2＋Bxy＋Cy2＋Dx＋Ey＋F=0）were used for curve fitting the corneal surface respectively. The relative merits among three fitting curves were analyzed. Finally,the eccentricity（e）obtained by corneal topography and conic section were compared with paired t-test. RESULTS：Five edge detection algorithms all had continuous coordinates which indicated the edge of the corneal surface. The ordinates of manual identifying were close to the inside of the actual edges. Binomial curve was greatly affected by tilt angle. Polynomial curve was lack of geometrical properties and unstable. Conic section could calculate the tilted symmetry axis,eccentricity,circle center,etc. There were no significant differences between ＇e＇ values by corneal topography and conic section（t=0.9143,P=0.3760 〉0.05）.CONCLUSION：It is feasible to simulate the corneal surface with mathematical curve with Matlab software. Edge detection has better repeatability and higher efficiency. The manual identifying approach is an indispensable complement for detection. Polynomial and conic section are both the alternative methods for corneal curve fitting. Conic curve was the optimal choice based on the specific geometrical properties. 展开更多

Dual-pumped microring-resonator-based optical frequency combs(OFCs) and their temporal characteristics are numerically investigated and experimentally explored. The calculation results obtained by solving the driven and damped nonlinear Schr?dinger equation indicate that an ultralow coupled pump power is required to excite the primary comb modes through a non-degenerate four-wave-mixing(FWM) process and, when the pump power is boosted, both the comb mode intensities and spectral bandwidths increase. At low pump powers, the field intensity profile exhibits a cosine variation manner with frequency equal to the separation of the two pumps, while a roll Turing pattern is formed resulting from the increased comb mode intensities and spectral bandwidths at high pump powers. Meanwhile, we found that the power difference between the two pump fields can be transferred to the newly generated comb modes, which are located on both sides of the pump modes, through a cascaded FWM process. Experimentally, the dual-pumped OFCs were realized by coupling two self-oscillating pump fields into a microring resonator. The numerically calculated comb spectrum is verified by generating an OFC with 2.0 THz mode spacing over 160 nm bandwidth. In addition, the formation of a roll Turing pattern at high pump powers is inferred from the measured autocorrelation trace of a 10 free spectral range(FSR) OFC. The experimental observations accord well with the numerical predictions. Due to their large and tunable mode spacing, robustness,and flexibility, the proposed dual-pumped OFCs could find potential applications in a wide range of fields,including arbitrary optical waveform generation, high-capacity optical communications, and signal-processing systems. 展开更多

An optical bandwidth analysis of a quantum-well （16 nm） transistor laser with 150-μm cavity length using a charge control model is reported in order to modify the quantum-well location through the base region. At constant bias current, the simulation shows significant enhancement in optical bandwidth due to moving the quantum well in the direction of collector-base junction. No remarkable resonance peak, limiting factor in laser diodes, is observed during this modification in transistor laser structure. The method can be utilized for transistor laser structure design. 展开更多

A liquid argon detector,consisting of 2.2 metric tons of liquid argon,is used to observe a significant alteration in the scintillation light yield of liquid argon while maintaining a high value for the slow decay time.The absorption effect due to trace impurities on 128 nm photons during vacuum-UV light transmission can account for this phenomenon.This explanation is substantiated by a combined analysis of data pertaining to variations in light yield and slow decay time with impurity concentration.The relationship between the light absorption length in liquid argon and detector light yield is assessed by employing GEANT4 detector simulations.The measured light yields suggest a reasonable range for the light absorption length,approximately 3-5 m or 8-10 m,as observed in two purification experiments.To enable future large-scale liquid argon detectors to achieve comparable light yields,it is imperative to significantly enhance the light absorption length of liquid argon. 展开更多

Visual aesthetics is a key metric of semi-transparent organic photovoltaics(ST-OPVs)for building-integrated solar windows,yet previous studies have primarily focused on the compromise between efficiency and transparency.In this work,we address the overlooked aspect of full visual aesthetic control of organic solar windows,particularly the bidirectional reflected color for architectural harmony,via designing ST-OPVs with the double-sided ultra-thin Ag/TeO2 transparent electrodes.Such a design facilitates full-spectrum color tunability and covers the whole standard color gamut of CIE coordinates on both surfaces of the device,as achieved simply by adjusting the thickness of each layer.Meanwhile,the resulting devices exhibit neutral transparency(16.6%–27.0%)and competitive efficiency(8.1%–9.2%).Moreover,the device delivers strong capacity for flexible device,and demonstrates flexibility-adaptive coloration and curvature-enhanced aesthetics.Therefore,this work presents an ST-OPV design featuring full visual aesthetics and considerable performance,paving the way for the commercialization of organic solar windows for building-and vehicle-integration. 展开更多
